ToaZZ whom it may concern.-

Be it known that I, GEORGE H. LUTHER, a citizen of the United States,residing at Olean, in the county of Cattaraugus and State of New York,have invented certain new and useful Improvements in Oil-Well PumpingPower; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to a new and useful improvement in pumping powersor devices for operating the pumps of oil-wells; and it consists in theconstruction hereinafter pointed out.

In the annexed drawings, Figure 1 represents a plan view of the device;Fig. 2, an end view, partly in section; Fig. 3, a diametric section;Fig. 4, a detail of one corner, and Fig. 5 another detail showing thecorner-support.

In the drawings the letter A represents a suitable frame madequadrilateral. This frame has a bridge-piece at the center, from whichextends the center stud a, projecting upwardly therefrom and madehollow, as at a. The circular bearing a is arranged around the stud a.Resting upon this bearing a is the hollow hub 11 of the main wheel B,and between this hub b and the stud a are placed balls or rollers G.This wheel B has on its under side the flaring circular part 1) near itscircumference and beyond this part b the plain circular surface'orbearing 6 having a continuation of the flare of the toothed part b. Uponthe top the wheel B has the plain circumferential bearing 6 The hub andthe periphery of the wheel B are connected by spokes b Off from thecenter the wheel B is provided with a stud d, on which loosely fits adisk D, having a number of places d, where are secured the rods (1 whichare connected with,

bridge-piece supporting the stud a, and has a beveled pinion f 2 toengage the toothed part b of the wheel.

Just above one bearing f the frame A has a projection 0, in which is journaled a roller G, having the beveled face g, the roller being spacedso far from the bearing f that the periphery of the wheel A may comebelow this roller G, the face of the latter bearing upon thebearing b ofthe wheel. 7

Power is applied to the shaft F,v and through the pinion f 2 the wheel Bis turned. As it turns it carries around the disk D, and through therods (1 the different pumps are operated; This much of the device is oldand Well known; but in practice it is found that in operating such adevice there is an irregularity of actlon, especially when only thepumps connected to one side of the disk are in operation, and the devicepulls up on one side. To obviate this difliculty, I have applied myimprovements. In operating a device such as shown and described in thiscase the rollers E hold the wheel B truly in a horizontal plane andthere is no wabbling, though only a part of the pumps be in operation.At the same time the roller G, bearing on top of the periphery of thewheel, prevents any jumping and holds the wheel firmly to its work.

It will be noted that in the foregoing construction the shaft F,carrying the pinion f extends under the wheel B and past the center ofthe same. In this way a compact structure with a long bearing orbearings remote from each other may be provided for the shaft F. Thisconstruction, while advantageous so far as the shaft F is concerned,necessitates a short central bearing for the wheel B. The rollers E andG therefore are peculiarly advantageous in this construction in thatthrough their use in maintaining a uniform angular relation between thewheel B and the axis of the stud the length of the stud is notimportant.

I am made aware that a horse-power for gin-mills, &c., is old in whichthere is a frame supported upon three antifriction-rollers and havingone on top,the last and one of the lower rollers gearing to operate themill. In this device the movement is always steady and the same withoutdanger of any wabbling.

In my device, as already stated, according tothe varying load upon thedevice there is a tendency to wabble or pull the device to one side.This I avoid not simply by using antifriction-rollers, I but rollerswhich take the thrust of the main wheel in opposition to the pull of thepump-rods, as this pull Varies. Therefore there are used four of theseunder rollers, so that at whatever angle or line of direction the pullmay come there will be a balanced resistance by at least two rollers,and consequently there will be no wabbling or tippin of the main wheel.

What claim is 1. In a power, the combination of a frame provided withthe journal-boxes f and the bridge-piece arranged between the boxes; amain geared wheel rotatively mounted on said bridge-piece; a connectingmeans eccentrically mounted on said wheel; a drive-pinion in mesh withsaid wheel; a shaft on which said pinion is mounted journaled in saidboxes and extending under said bridge-piece e and by the center of saidwheel.

2. In a power, the combination of a frame provided with thejournal-boxes ff and the bridge-piece arranged between said boxes; amain geared wheel rotatively mounted on said bridge-piece; a connectingmeans eccentrically mounted on said wheel; a drive-pinion in mesh withsaid wheel a shaft on which said pinion is mounted journaled in saidboxes and extending under said brid e-piece and by the center of saidwheel; and rollers operating upon said wheel to maintain it in fixedangular relation to the power-frame.

In testimony whereof I affix my signature in presence of two witnesses.
